Patent DE-3834998-A1 (DE)
Title: Angle drilling and milling arm
Inventor: FELDER ADOLF
IPC: B23B39/00
Filed: 1988-10-14
Abstract: To make recesses (e.g. a bore) starting from a hollow space (5), an angle arm (3) provided with a tool (2) is put into the hollow space (5) of the workpiece (6). In known angle arms, high bending moments arise which impair the accuracy of the machining and impair the machining performance (feed performance). The novel angle arm (3) is intended to largely avoid the bending moments described. On the side remote from the tool (2), the angle arm (3) is supported against the wall (4) of the hollow space (5) by an adjustable supporting element (1). By a coupling (12) with a control element (11), the position of the supporting element (1) relative to the angle arm (3) changes in such a way that the angle arm (3) is also supported during the machining operation. The angle arm (3) permits accurate machining of, for example, transverse bores in a workpiece (6). <IMAGE>

Patent DE-3843075-A1 (DE)
Inventor: KAULE WITTICH DR
IPC: G07D7/023
Filed: 1988-12-21
Abstract: A security document is equipped with a security element in the form of a thread or strip that is characterized by, among other things, the property of electrical conductivity. The security element is provided for this purpose with a metal coating associated with a second layer that is also electrically conductive but made of a material that maintains its electrical conductivity in spite of mechanical stress such as bending, stretching, etc. Breaks in the metal layer which might occur when the thread is being embedded in the security document or during daily use thus do not result in a complete interruption in the electrical connection, but are bridged by the second, electrically conductive layer.

Title: Rotary tools in sausage-meat mincer - have mobility in both axial directions to prolong service life and protect prod. from excessive heating
Inventor: NEUNER HANS
IPC: B02C18/36
Filed: 1989-11-28
Abstract: Meat and other sausage-filling components fed from a hopper (24) are chopped by a cutter (10) rotating relative to and above fixed apertured disc (18).

IPC: E04B1/48
Filed: 1990-09-20
Abstract: To produce a tension- and shear-resistant connection of two beams, in particular in the form of glued laminated timber members, with mutually crossing grains of the two beams to be connected, in a process for the connection of such timber elements a bore is produced through the face of the cross-cut end of the first beam and a spindle made of metal and equipped with a thread is bonded into the bore by means of epoxy resin, an end portion of the spindle projecting above the face. On connecting the two beams, the end portion of the spindle reaches through a corresponding bore in the second beam, at the end of which is formed a counterbore for receiving a nut which can be screwed onto the end of the spindle. A ring made of metal is arranged in the connection plane of the two beams concentrically to the spindle in such a way that one ring half extends into an annular groove in the face of the first beam and the other ring half extends into a corresponding annular groove in the contact face of the second beam. After tightening the nut on the spindle, a tension- and shear-resistant connection of the beams is produced. <IMAGE>
